Zuurvorming tijdens gemengde zuurgisting wordt aangetoond met de methylroodtest (MR-test).
Gemengde zuurgisting produceert veel zuur (pH<4,4), wat na toevoeging van de methylroodoplossing leidt tot een dieprode kleur (positief). Als er geen gemengde zuurgisting plaatsvindt, is er weinig zuur aanwezig en ontstaat een geel/oranje kleur (negatief).
De methylroodtest maakt deel uit van de Bunte-serie voor het differentiëren van bacteriën, in het bijzonder uit de groep Enterobacteriaceae.

Questions about Methylrood-supplement, voor microbiologie, 100 ml, glas
What is this article?
Methylrood-supplement, voor microbiologie, 100 ml, glas is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Dehydrated culture media (agar & broth bases), inside Culture media & microbiology, in Microbiologische media.
A dehydrated medium is a powder the laboratory dissolves, sterilises and pours. The formulation name, the supplements it still needs, and the grams per litre are the specification. Two powders with similar names, one selective and one not, grow different organisms.
A culture medium is the food and the solid or liquid home of a microorganism. Dehydrated media are powders the laboratory dissolves and sterilises. Ready-to-use plates and tubes are already that. A Petri dish is the plate. Selective media let one kind of organism grow and hold another back. The formulation and the supplements, not the colour of the agar, are the specification. Reference strains are at ATCC. Methods are on PubMed. Biosafety practice is the WHO laboratory biosafety topic.
